Estimates based on models

Preferred temperature (Ref. 123201): 4.7 - 8, mean 6 °C (based on 159 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
營養階層 (Ref. 69278):  4.1   ±0.59 se; based on food items.
回復力 (Ref. 120179):  低的, 最小族群倍增時間4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High vulnerability (62 of 100).
價格種類 (Ref. 80766):   Medium.
Nutrients (Ref. 124155):  Calcium = 6.32 [0.98, 112.39] mg/100g; Iron = 0.274 [0.026, 3.186] mg/100g; Protein = 14.7 [13.2, 16.5] %; Omega3 = 0.7 [0.3, 1.8] g/100g; Selenium = 11.4 [2.3, 56.0] μg/100g; VitaminA = 12.9 [1.0, 162.0] μg/100g; Zinc = 0.352 [0.024, 3.890] mg/100g (wet weight); based on nutrient studies.
